The correct answer highlights a significant cognitive deficit often associated with left hemisphere strokes, which primarily affect language processing due to the location of key language centers, such as Broca's and Wernicke's areas. Patients with left hemisphere strokes frequently experience difficulties with understanding language, known as receptive aphasia, and may also struggle with producing coherent speech, referred to as expressive aphasia. This cognitive impairment arises because the left hemisphere is typically responsible for language capabilities in right-handed individuals and many left-handed individuals as well.

In terms of context, a stroke affecting the left side of the brain disrupts communication pathways that are crucial for both understanding and generating language. Therefore, this answer effectively captures the expected cognitive deficit given the patient's medical background. Other options describe deficits related to different areas of the brain or cognitive functions. For instance, problems with spatial awareness and visual perception are more commonly linked to right hemisphere strokes, which manage nonverbal tasks and spatial awareness. Similarly, motor function loss could occur in the right arm due to damage to areas controlling motor output but does not primarily involve cognitive deficits. Thus, the decline in language skills stands out as the most likely cognitive deficit in this scenario.
